TIMER FOR INTERNALCOMBUSTION ENGINES.

To all whom it may concern:

Be it known that I, JEROME F. SHERBINO, a citizen of the United States,residin at ountain Lakes, county of Morris, and tate of New Jersey, haveinvented certain new and useful Improvements in Timers forInternal-Combustion Engines, of which the following is a specification.

his invention relates to timers for internal combustion engines, beingintended more particularly for use on multi-cylinder engines. r

The invention has for an object to provide a timer characterized byextreme simplicity of construction and efliciency of-operation, and byan arrangement of parts acting to protect the electrical conductors andcontact members. I

For further comprehension of the invention and of the object andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claim in which thevarious novel features of the invention are' more particularly setforth.

-Figure l of the drawings is .a part side elevation and part axialsection of a timer constructed according to my invent-ion.

Fig. 2 is a. horizontal section on the line 2-2 of Fig. l.

The contact members of my improved timer are inclosed within acylindrical casing 1 which is open at one end and is closed at itsopposite end by an integral cap por tion 2 of flattened conical form. Asshown in Fig. 1 the outer conical surface of the cap forms a greaterangle with the axis of the cap, than the inner conical surface, so thatthe conical wall of this cap' tapers in thick ness from bottom to top,being of much greater thickness at the bottom than the cylindrical wall1, thus providing an annular surface 3 in a axis of the casing.

This surface provides a runway for the rotating contact of the timer,which contact Specification of Letters Patent.

exceedingly simple construction and plane transverse to the PatentedSept. 27, 1921.

Application filed October 15, 1919. Serial No. 330,818.

. here comprises a stud 4 slidable in a socket 5 formed 1n a head 6 onthe end of an arm 7 secured by any suitable means to the usual shaft 8,a spring 9 in the socket 5 pressing the stud outward.

Carried by the cap portion 2 are a series of fixed contacts eachconsisting of a flat segmental plate 10 set into the face 3 flushtherewith and evenly spaced therearound.

hese plates are formed with studs 11 which project through the cap 2parallel to the axis thereof and terminate in screws 12 providingbinding posts.

As will be understood the casing is formed of insulating material and inconstructing the same I prefer to mold the fixed contacts therein. Foradjustment of the casing in the usual manner to change the timing Isecure a bracket 13 by screws 14 to the outside of the. casing, thisbracket. having a sleeve 15 adapted to receive the usual adjustmg means.

As will be apparent I have provided an arready leading for properinclosing of member.

rangement which rovides for of the wires and the moving contact I claim-A timer comprising a conical cap having conical inner and outersurfaces, the said outer surface forming a greater angle with the axisof the cap than said inner surface,

cap a thickness decreasing gradually toward the apex of the cap, thebase of the cap having an internal surface transverse to said axis andcontact members at said surface, and a casing extending from the outerportion of said base in the direction opposite to the cap, at a greaterdistance from the axis than said contact members.

In testimony whereof I have affixed my signature.
